Sendmail < 8.10.0 mail.local Newline Handling Remote DoS



The remote host is vulnerable to a Denial of Service (DoS) attack.


The remote Sendmail server does not properly identiy the '. ' string which identifies the end of message text. An attacker may use this flaw to remotely corrupt user mailboxes by sending a message line which is 2047 characters long and end in '. '.


Install sendmail 8.10.0 or higher.
